Time to come along with Eric O at the SMA shop as he has a look at this 2007 Chevy Silverado 1500. Every light on the dash is on but we are going to focus our efforts on the check engine light. The truck is running really rich and his having problems controlling the fuel pressure. Let's see if we can get to the bottom of this!

One thing I have learned watching your videos is how lucky I am that I don't have electrical problems in my 2002 Chevy Silverado. For the first 11 years that thing rode the salt roads of Indianapolis winters, and there was nothing my young sons liked more than when I would drive through one of those salton puddles! Make it splash daddy! I now live far away from salt, but am amazed that I have never had a problem with the electrical system. As I look back the only thing I can think that would have made a difference was regularly praying for the vehicle and thanking God for providing it.

I have a 04 Silverado 1500 with the P0172, 175 codes, aside for the FPCM you know of any common triggers for these codes. After watching this vid I checked the fuel pressure on the fuel rail and was getting around 60psi. Could the fuel pressure sensor be bad even though I have the correct pressure at the engine?
reply

Hey Eric any idea why my fuel pressure shoots up at idle to 59 instead of the normal 43psi like this truck and gives me a flashing rich p0300? I get open loop fault when pressure goes high. Could it be this module or the ecm sending that command? Thanks love your videos.

28: 52 Wouw what the devil is that, looks like something u put on a Christmas tree or something u built at the yunk yard out of necessity. That's a test light alright. Jeez Eric O. Warn me before u dig stuff like this from the bottom of your tool box.

another great video! also just wanted to tell ya I'm from Attica (not an inmate lol. we were in your area on Saturday (10-1-16) for a soccer game. stopped by but you were closed. I can't wait to shake your hand. love the videos!

Good job. Just one minor issue. were you really checking the cable ground? Looked like you connected your factory load bank to the truck frame. Otherwise I'm a big fan of using light bulbs as current testers and stand ins for fuses.

Great video on the repair. I like how you were able to do the ECU flashing in house.
How many hours did you charge for the diag and repair?
Thought I was gonna get to see the Autel do some ECU flashing. Still a awesome video.

What if this module was programmed wrong by the last guy? Why not try to program this first before ordering a new one? May be this was wrongly programmed to take the 12V FP sensor and convert in to 5V signal to the ECM.

Hi, always love watching your videos. You work on a lot of silverados like my truck. I heard you say NY. Are you close to Buffalo, NY? I would be happy to bring my truck to your shop if you are close enough. Thank you
